In any book, the author must introduce the characters, the situation, and the basic elements of the setting, but in fantasy and science fiction you might have a viewpoint character in the first chapter who isn't even human, living on a planet that isn't even in this universe. The very laws of physics might be different, never mind the differences in culture, history, civilization, and everything that goes along with that: systems of measurement, idioms, naming conventions, philosophical principles, mathematics, science...speculative fiction strives to introduce and immerse a reader in a world that might be completely different from that with which we are familiar.
As I was writing several of the scenes in the later episodes of Blood Magic's first season, I was struggling to describe what, exactly, Prime Wezzix and Borivat do all day. Specifically, I had a discussion in episode eight about Merolate's budget. As I was writing it, I was trying to make it realistic, but I found myself wondering what a budget for a nation-state at a level roughly comparable to Italy in the thirteenth or fourteenth century might reasonably include.
This post is primarily intended as an educational one, to discuss some of the terminology and thought-processes involved in materials science, but it was inspired by world-building considerations. As you may recall, if you've been following along with what I've been reading (and my regular book reviews), I recently read a book called The Substance of Civilization, which detailed how the materials to which our species has had access have shaped the course of cultural evolution over the past ten thousand years. It prompted me to think in more detail about choice of materials and construction techniques in world-building.
I admit that I've never participated in NaNoWriMo, despite it being one of the most popular events for the past several years for aspiring writers. The goal of it is to help people establish a writing habit, so it's not that I don't support the mission. In fact, I post writing prompts here on the site precisely because I want to encourage people to write more. And the idea of basically free-writing a short novel in the course of a month isn't a bad one. As unreasonable as it might sound, writing fifty thousand words in a month is not all that much of a stretch, if you're willing to make a routine out of it.
Creative writing, or the speculative fiction genre, has long leveraged something called the MICE quotient. I first came across this when I was reading an Orson Scott Card book on how to write science fiction and fantasy (I think it was even titled How to Write Science Fiction and Fantasy). The premise is that stories in the speculative fiction genre can be broadly binned as having one or more of four, primary drivers: milieu, idea, character, and event. Although most good stories will incorporate multiple of these components, with different ones emphasized at different times, there is usually one that drives the story forward.
